المواصفات الفنية
Precision Cold-Rolling Technology
The formation of aluminum fins requires a delicate balance of pressure and flow. Nexmek rolling blades are profile-ground using CNC precision to ensure that the extrusion process is smooth and consistent, preventing micro-fractures in the aluminum sleeve while maximizing the surface area for thermal exchange.
- Advanced profile geometry for uniform fin height
- Low-friction design to prevent aluminum adhesion
- Engineered for high-volume industrial production
